Supabase raises $150M more and buys Turso for agent databases

Supabase said Friday it raised $150 million in new funding led by GIC and is acquiring Turso, whose architecture spins up cheap per-agent databases as AI coding tools flood its Postgres platform.

Coding agents are no longer a side channel for app backends — Supabase says most new databases on its platform are already spun up by AI tools. Paying for Turso’s per-agent database architecture is a bet that the next wave of software won’t be one database per company, but millions of short-lived databases per agent swarm.

On Friday, 2 October 2026, Supabase said it raised $150 million in new funding and is acquiring Turso. PR Newswire carries the release. The page stamps Oct. 2, 2026, 09:00 ET, which is 9:00 a.m. Eastern. The dateline is San Francisco. The source line is Supabase. The headline is “Supabase Announces $150M in New Funding and Turso Acquisition.” The line under the headline says the agentic infrastructure leader is adding support for millions of new agents each month as AI accelerates software creation. Agentic, on this page, means software agents do the work. An agent is a program that can take a next step, not only answer in a chat. Infrastructure, here, is the backend those programs run on. A backend is the database and the services behind an app, the part a person does not see. Supabase calls itself the leader in agentic infrastructure and an open source Postgres development platform. Postgres is a widely used open-source database. “Leader” is the company’s description of itself. Those lines are the wire’s.

Who put the money in, as the release states it. The $150 million is led by GIC. Alphabet’s independent growth fund, CapitalG, is participating, along with IronArc and SquarePeg. A lead investor is the firm that anchors the round. Participating means those three are in it. The release names the four. It does not say how much each one put in. It describes CapitalG only as Alphabet’s independent growth fund. It does not describe GIC, IronArc, or SquarePeg beyond the names. The investment, the release says, comes just four months after the company’s $500 million Series F, as AI coding tools and agents drive another major uptick in growth. A Series F is a late round of private funding, after earlier rounds. Four months before this Friday is early June. The release prints the $500 million and the four months. It does not print a price for the whole company on this page, and it does not give this $150 million a series letter of its own. Those lines are Supabase’s, on the wire.

What the release says the round and the acquisition are for. They will accelerate Supabase’s continued product development around agent-driven databases. An agent-driven database, in that sentence, is a database an agent creates or runs because it needs one. The same paragraph says this round will also provide liquidity for employees, which the founders think is an important and vital part of being the best company for engineers. Liquidity, here, means some of what employees hold can be turned into cash. The release does not say how much cash, which employees, or what share of the $150 million that is. Those lines are the release’s.

Paul Copplestone, co-founder and chief executive, is quoted on the release. “The past year has been the fastest growth in our history by a wide margin. We’re grateful for the support from our existing and new investment partners like CapitalG. Their connections to the broader Alphabet ecosystem will be invaluable as we build for our next level of growth,” he said. He also said: “The future is agents and the architecture Turso provides will help us accelerate Supabase as the backend platform for supporting that future.” That quotation is his, in the release. “Fastest growth” and “invaluable” are his words. The release does not print a growth percentage inside the quotation.

The counts in the section titled “Investing in builders and the Supabase community.” Supabase says it is now adding more than 1 million users and 4 million databases per month, with 70 percent of new databases created by agents or AI-driven tools. More than 1 million users a month is the company’s count of new users. Four million databases a month is its count of new databases, not a count of companies. Seventy percent is 7 in 10 of those new databases. The release says the growth follows a 600 percent year-over-year increase in databases reported in June, when agents were already deploying the majority of new databases on the platform. Year-over-year means compared with the same stretch a year earlier. A 600 percent increase means the new count is seven times the old one: the added amount is six times the earlier count. That seven-times line is arithmetic on the release’s 600 percent. The release states 600 percent. It does not print the two counts behind it. Majority means more than half. The release does not print a June percentage. The 70 percent figure is the one it prints for now. Those figures are Supabase’s, in this release.

What the release says is driving the new databases. Claude Code, Codex, and other AI coding tools are expanding both the number of people who can build software and the amount of software they can create. Supabase says it has seen successive waves of growth. First, AI app builders opened software development to a broader audience. Then coding agents became capable of building increasingly sophisticated applications, and growth accelerated again. An app builder, here, is a tool that produces an application from a prompt. A coding agent writes and changes code. The company’s stated goal is to become the first place developers and agents turn when they need backend support. The release names Claude Code and Codex. It does not say those products are Supabase’s, and it does not print a share of the 70 percent for either one. Those lines are the release’s.

Derek Zanutto, a general partner at CapitalG, is quoted on the release. “Supabase has established itself as the critical open infrastructure layer powering the AI revolution,” he said. “We’re proud to back one of the fastest growing private database companies on the planet as Paul and the team empower millions of developers and agents to build at unprecedented speed.” A general partner is a senior investor at the firm. “Critical,” “fastest growing,” and “on the planet” are his words, in the release. The page does not print a ranking under that quotation.

Why the release says Supabase is buying Turso. As AI labs and builders keep scaling agentic deployments, the need for large numbers of databases compounds. The release says an agent should be able to create a database instantly, and that platforms should be able to launch enormous numbers of isolated databases without the overhead of provisioning a dedicated machine for each one. Isolated means one agent’s data sits in its own database, apart from the others. Provisioning a dedicated machine means standing up a separate server for every database. A deployment, here, is a live setup of those agents. The release says Turso is a platform that lets developers reach higher volumes of databases for agentic workloads. A workload is the job the database is doing. Those lines are the release’s. It does not print a purchase price.

What the release says Turso’s architecture does. The team built an architecture that offers databases at a low cost. It provisions on-demand per-agent databases in the public cloud and in BYOC, for customers like Superhuman, Sauna.ai, CTO.new, and Mastra. On-demand means the database is created when it is needed, rather than reserved ahead of time. Per-agent means one database for one agent. The public cloud, here, is the vendor’s cloud. BYOC is the release’s abbreviation. It is usually read as bring your own cloud: the database runs in the customer’s own cloud account. The release prints BYOC and does not spell those words out. The four names are examples. The release says “customers like” those four. It does not say they are the only customers, and it does not say they became Supabase customers on Friday morning. “Low cost” is the release’s phrase. It does not print a price per database. Those lines are Supabase’s, on the wire.

What happens to the company and the people, as the release states it. Both companies, it says, focus on open source, on developer experience, on a willingness to tackle hard problems, and on a shared view of how infrastructure will change for agentic AI. Open source means the code is published so other people can read it and run it. The Turso platform will continue to operate, with what the release calls a clear graduation path into the rest of the Supabase ecosystem. A graduation path, in that sentence, is a route from a Turso database into Supabase’s other products. The release does not print a date for that move. Glauber Costa, founder of Turso, will join Supabase as head of agentic services, alongside co-founder Pekka Enberg and the rest of the Turso team. Head of agentic services is the title the release gives Costa. The release does not print a title for Enberg.

Costa is quoted on the release. “From the start of our journey, I’ve had as a goal to serve upwards of a billion databases to our customers. Being a part of Supabase, with its gargantuan developer success and ever-growing partner ecosystem will bring this goal closer.” Upwards of a billion is his goal for how many databases to serve. It is not a count the release prints for Supabase today. The about box’s figure for developers, below, is more than 13 million people, not a billion databases. “Gargantuan” is his word. That quotation is his, in the release.

Who the about box says Supabase is. It repeats that Supabase is the leader in agentic infrastructure and an open source Postgres development platform. More than 13 million developers use it to build and scale applications. The company was founded in 2020. It says it provides a complete backend: a Postgres database, authentication, storage, edge functions, real-time subscriptions, and vector search, alongside a growing marketplace of more than 100 integrated partner tools. Authentication is sign-in. Storage is files. An edge function is a small program that runs close to the user, rather than in one central data center. A real-time subscription pushes a database change out to an app as it happens. Vector search finds items by meaning, the kind of lookup many AI apps use. A partner tool is another company’s product wired into that marketplace. Thirteen million and more than 100 are the about box’s figures. The box points readers to supabase.com. It does not print a price for the company.

The picture is a split graphic. The left half is bright green. It shows the Turso wordmark, a stack of disk-shaped database marks, and the lines “Per-agent databases” and “Public cloud and bring-your-own-cloud.” The right half is white. It shows “$150M,” “New funding,” “Led by GIC,” then “CapitalG · IronArc · SquarePeg,” and “Acquires Turso.” The frame does not print a calendar date. It is a graphic built from the Turso mark and the funding lines on the release. It is not a photograph of an office, and it does not print a price for the company.

In plain terms, Supabase said on Friday that it raised $150 million led by GIC, with CapitalG, IronArc, and SquarePeg in the round, four months after a $500 million Series F. It also said it is acquiring Turso so an agent can get its own database on demand, in the public cloud or in a customer’s cloud, without a separate machine for each one. The company says it is adding more than 1 million users and 4 million databases a month, and that 70 percent of the new databases come from agents or AI tools. Those counts are Supabase’s. Costa and Enberg are joining, Costa as head of agentic services, and the Turso platform keeps running. The release does not print a valuation for this $150 million, a purchase price for Turso, or a dollar figure for the employee cash.
